steamist sms-60 electric sauna heaterThe Steamist SMS-60 is a 6,000 watt (6KW) electric sauna heater designed for medium sized home saunas between 170 and 300 square feet (length x width x height).

Steamist is a steam shower and sauna company headquartered in East Rutherford, NJ.

Saunas using the SMS-60 should be between 28 and 40 feet with a ceiling height of at least 74″.

The SMS is generally a good size for in home or outdoor saunas built for 3-5 people.

Minimum clearances for installation are 4″ to a wall or 2″ to a fence made of cedar or other softwood.  Consult the manual for other minimum clearances and instructions.

The SMS models are wall mounted electric sauna heaters.  Though it can be mounted close to a corner, it is not a true corner mount system like the Saunacore SE6.

The unit does not come with an electric plug and should be wired by a qualified electrician.  Make sure your electric service is adequate and you have room on your electric panel.  According to the manual, failure to have the work performed by a licensed electrician will void the warranty.

The stove is designed to handle the traditional sauna practice of dropping water on the rocks to create steam.
